How to choose the flu vaccine? Let’s take a look at the new version of China Influenza Vaccination Technical Guide (2023-2024).

  Influenza (hereinafter referred to as "influenza") is an acute respiratory infectious disease caused by influenza virus, which is harmful to human health. People are generally susceptible to influenza virus, and the high-risk groups such as pregnant women, infants, the elderly and patients with chronic diseases are more harmful after being infected with influenza. Influenza outbreaks are prone to occur in places where people gather, such as schools, kindergartens and nursing homes. Vaccination against influenza every year is an effective means to prevent influenza and reduce the burden of influenza-related severe illness and death, which can reduce the health hazards caused by influenza-related diseases and the run on medical resources. In order to better guide the prevention and control of influenza and the use of vaccines in China, on September 5th, China Center for Disease Control and Prevention issued the Technical Guide for Influenza Vaccination in China (2023-2024).
  The updated contents of the new edition of the guide mainly include the following aspects:
  First, new research evidence has been added, especially the research results in China, including the burden of influenza disease, vaccine effect, vaccine safety monitoring, vaccine vaccination cost-effectiveness and so on;
  Second, the policies and measures on influenza prevention and control issued by the National Health and Wellness Commission and the National Bureau for Disease Control and Prevention in the past year have been updated;
  Third, the types of influenza vaccines listed in China in 2023-2024 were updated;
  Fourth, the trivalent and tetravalent influenza vaccine components of this year were updated;
  Fifth, the influenza vaccination recommendations for 2023-2024 were updated.
  The guideline suggests that all people who are over 6 months old and have no vaccination contraindications should be vaccinated against influenza. Combined with the epidemic situation of influenza and the prevention and control strategy of multi-disease prevention, the harm of influenza is reduced as much as possible, and the following key and high-risk groups are recommended to be vaccinated in time:
  1 medical personnel, including clinical rescue personnel, public health personnel, health and quarantine personnel, etc.;
  2. Older people aged 60 and over;
  3. People suffering from one or more chronic diseases;
  4. Vulnerable people and employees in gathering places such as old-age care institutions, long-term care institutions and welfare homes;
  5. Pregnant women;
  6. Children aged 6-59 months;
  7. Family members and caregivers of infants under 6 months old;
  8. People in key places such as kindergartens, primary and secondary schools and supervision places.
  In terms of inoculation times, it is suggested that:For inactivated influenza virus vaccine, children aged from 6 months to 8 years old, if they have not been vaccinated with influenza vaccine before, should be vaccinated twice for the first time, with an interval of ≥4 weeks; In 2022-2023 or before, one dose or more of influenza vaccine will be vaccinated; Children and adults aged 9 years and above need only be vaccinated once regardless of whether they have been vaccinated with influenza before. For live attenuated influenza virus vaccine, no matter whether it has been vaccinated with influenza vaccine or not, only one dose is given.
  There are many flu vaccines, how to choose them?
  According to the types of influenza viruses, influenza vaccine can be divided into trivalent and tetravalent. Trivalent influenza vaccine includes three types of influenza viruses: H1N1, H3N2 and Victoria, which can prevent the infection of these three types of influenza viruses. The tetravalent influenza vaccine contains more Yamagata influenza virus B than trivalent influenza vaccine, which has not been popular for many years. According to the 34th week influenza surveillance data released by China National Influenza Center last week, the current epidemic strain is mainly A, accounting for more than 90%.
  At present, our city mainly supplies the following three types of vaccines:
  ? Tetravalent influenza virus split vaccine
  ? Trivalent influenza virus split vaccine
  ? Trivalent freeze-dried nasal spray live attenuated influenza vaccine
  Members of the public are advised to complete vaccination before the influenza epidemic season. For people who can be vaccinated with different types or different manufacturers of vaccine products, the recipients (or their guardians) can voluntarily choose to vaccinate any kind of influenza vaccine, without priority recommendation. In the same epidemic season, people who have completed the whole vaccination according to the vaccination procedure do not need to be vaccinated again. Pregnant women can be vaccinated with inactivated influenza vaccine at any stage of pregnancy and use it according to the instructions.
  

Former Google scientist started a business, but the IPO was cold! Volkswagen China lost 90% of its money and Sequoia became one of the biggest winners.

  Despite the aura of "AIGC" and "big model", Mobvoi’s valuation has stagnated in five years, and its listing has suffered a break, once falling by more than 20%.

  Before IPO, Mobvoi raised a total of 233 million yuan, with the highest valuation of 757 million yuan. Volkswagen China, which contributed the most, lost nearly 90% when it withdrew in 2021. Sequoia China, the earliest investor, can be described as one of the biggest winners. It used only $3.465 million, that is, it gained a profit of $29.855 million and a stock right worth $74.55 million, with a book income of nearly 30 times.

  It is noteworthy that after the launch of the self-developed model "Sequential Monkey", the annual compound growth rate of AIGC business income in Mobvoi from 2021 to 2023 exceeded 300%, and the number of paying users increased from 63,000 to 410,000. However, considering the high training cost of the big model, it is worth paying attention to whether Mobvoi, which will spend only 155 million yuan on R&D in 2023, can maintain its technological superiority.

  On April 24th, Mobvoi (02438.HK), known as "the first AIGC share", was listed on the Hong Kong Stock Exchange. As the first profitable AI-Generated Content company listed in Hong Kong at China Grand Model Raceway, its business situation and secondary market performance attract people’s attention.

  However, after the opening of the day, Mobvoi suffered a break, and its share price once fell by more than 20%. In the afternoon, it rebounded strongly and finally closed down by 3.16%.

  Since its listing, Mobvoi’s share price has dropped by 2.11% compared with the issue price, and its market value has dropped to HK$ 5.548 billion, which has also cast a shadow over its subsequent trend.

  01

  Behind the "AIGC First Share": Volkswagen’s investment in China exploded by 90%

  Before the IPO, Mobvoi completed a total of seven rounds of financing, with a total financing amount of US$ 233 million, and its valuation rose from US$ 5.01 million in the A round in 2013 to US$ 757 million in the D-2 round (Table 1). In other words, Mobvoi’s current market value of HK$ 5.548 billion still has a gap of nearly 6% compared with its valuation five years ago.

  

  Although its share price is discounted compared with the primary market, according to the statistics of New Wealth, the only injured investor in the round of financing is Volkswagen (China) Investment Co., Ltd. (hereinafter referred to as "Volkswagen China").

  Volkswagen China is the largest investor in Mobvoi. In 2017, it purchased 289 million preferred shares of Mobvoi through its wholly-owned subsidiary, Volkswagen Finance Luxemburg S.A for US$ 140 million. In September 2019, it once again participated in the D-2 round of financing with US$ 15 million, and got 31 million D-2 preferred shares.

  However, Volkswagen China, which invested heavily in the project, soon chose to quit. In December 2021, Mobvoi repurchased all the shares held by Volkswagen China at a price of $17 million. Based on this calculation, the loss of Volkswagen China’s investment this time is close to 90%.

  Assuming that Volkswagen China has held shares so far, its investment loss will be reduced to 8.9% based on the issue price of HK$ 3.8 per share in Mobvoi, which is about 124 million USD.

  Among other investment institutions, Sequoia China, Zhenge Fund, SIG Haina Asia, Goer, etc., which were funded in the early stage, all earned a lot of income.

  After the listing of Mobvoi, the largest external shareholder is SIG Heiner Asia, holding 16.03%, while Sequoia China, Goer and Zhenge Fund hold 10.92%, 10.03% and 3.07% respectively.

  Sequoia China, who was the first to participate in Mobvoi’s A-round and A-1-round financing, is one of the biggest winners. In the A round of financing, Sequoia China acquired 161,675,300 shares of Mobvoi at a price of US$ 1.358 million, and the cost per share was only US$ 0.0084. In the A-1 round, Sequoia China once again got 53,889,600 shares at a price of 2,107,000 US dollars, with a cost of 0.039 US dollars per share.

  It is worth mentioning that in 2018, Sequoia China transferred 61.88 million shares acquired in Series A to two investors, namely GWC Robotics Investment Limited and So Artemis Limited, at a price of US$ 20.25 million and US$ 10.125 million respectively, and made a profit of US$ 29.855 million. The value of the remaining 153.68 million shares listed in Mobvoi is as high as $74.55 million. Based on this calculation, Sequoia China only spent $3.465 million, that is, it gained a profit of $29.855 million and a stock right worth $74.55 million, with a book income of nearly 30 times.

  Google, whose capital contribution is second only to that of Volkswagen China, invested $40 million and $1.87 million in the C and D-2 rounds of financing in Mobvoi respectively, with an average shareholding cost of $0.22 per share, which is still 120.5% higher than the IPO issue price.

  As the founder of Mobvoi, Li Zhifei holds 376 million shares of the company through Mobvoi AGI Limited, a wholly-owned company, with a shareholding ratio of 25.2%. At present, the stock market value is about HK$ 1.4 billion.

  Li Zhifei is a Ph.D. student in computer science at Johns Hopkins University in the United States. Before he founded Mobvoi, he worked as a research scientist at Google from May 2010 to August 2012, and was mainly responsible for the algorithm development of language translation models.

  In 2012, voice search, a new interactive technology, became popular after Apple Siri came out as an iPhone 4S built-in application. Li Zhifei also left Google and returned to China to establish Mobvoi.

  According to the prospectus, the services provided by Mobvoi focus on AIGC and voice interaction technology. According to the current business, it mainly includes three parts: AIGC solution, AI enterprise solution, intelligent equipment and accessories.

  Among them, the revenue of AIGC solution business, with AI dubbing assistant "Magic Sound Workshop" and AI digital person "Wonderful Yuan" as its main products, has increased rapidly, from 07 million yuan to 118 million yuan in 2021-2023, with a compound annual growth rate of over 300%.

  The revenue of AI enterprise solution business, which mainly focuses on automotive voice interaction solutions, increased from RMB 53 million in 2021 to RMB 226 million in 2022, and then decreased by 14.2% in 2023.

  The revenue of smart devices and other hardware businesses, mainly selling smart watches with TicWatch, dropped from 338 million yuan in 2021 to 164 million yuan in 2023.

  Since Mobvoi’s AIGC business has made rapid progress in recent years, why is its valuation stagnant? Why did Volkswagen China quit its shareholder ranks early?

  02

  Volkswagen China: From investing $140 million to clearing shares.

  Since the establishment of Mobvoi, its business has gone through the process of continuous exploration, and its development is mainly divided into four stages.

  The first stage is to try to develop voice search service software. In 2013, Mobvoi established the WeChat voice search service platform; In 2014, after Google launched Google Glass, Mobvoi launched "Mobvoi on Google Glass", a Chinese smart voice search application. However, with the failure of the Google Glass project, this application also stopped updating.

  In 2014, Mobvoi entered the second stage of development, that is, from software to hardware business, and its smart equipment and other accessories business also started.

  At that time, Mobvoi hoped to put voice search’s capabilities into products, and finally chose the smart hardware market-it first released Ticwear, the world’s first Chinese smart watch operating system, and then launched TicWatch in June 2015.

  At the same time, Mobvoi has also reached a strategic cooperation with Google, which will build the Ask App Store in all smart watches equipped with Android Wear system sold in China. Also in 2015, Google shot, and Mobvoi completed the C round of financing, with a valuation of 273 million US dollars, becoming a hot start-up in the AI market.

  TicWatch, as one of the few products with relatively perfect smart watch operating system in China at that time, was quickly favored by the market after its launch. In the "Double Eleven" sales list of JD.COM in 2015, TicWatch ranked third in the field of smart watches, second only to Apple’s i Watch and Motorola’s MOTO 360. Since 2016, Mobvoi has successively launched smart speakers, smart headphones and other products, and at the same time promoted the products to the sea.

  At the strategic new product launch conference held in 2018, Mobvoi not only iterated on smart watches, smart headphones, smart audio and other products, but also released the first mass-produced AI voice chip module "Wen Xin" in China in the face of the enterprise market, and said that it would open 20 new offline smart experience stores nationwide. However, with Huawei, Xiaomi, Glory and other giants stepping up the smart hardware market, Mobvoi’s competitive advantage in products has been gradually erased or even overtaken.

  It can be seen that during 2021-2023, the revenue of its smart devices and other accessories business dropped from 339 million yuan to 164 million yuan, accounting for 85% of the total revenue to 32.3%. In the same period, the number of its global distributors also dropped sharply from 101 to 39.

  It is not difficult to see that the weakening influence of Mobvoi in the smart device market is one of the reasons that restrict its valuation growth.

  The protagonist in the third stage of Mobvoi’s development is Volkswagen China, an automobile giant that brings Mobvoi an opportunity to explore the B-end market.

  Back in 2017, Volkswagen China not only invested US$ 140 million in Mobvoi, but also invested US$ 40 million each, holding 50% of the shares, and set up a joint venture company Mobvoi JV, with the goal of realizing the application of multiple AI technologies, including speech recognition, in several factories and models of Volkswagen in China. In layman’s terms, it relies on Mobvoi’s voice interaction technology to provide car voice assistant for Volkswagen China, as well as some additional functions such as personalized push, GPS and in-car entertainment information system.

  In 2020, Volkswagen’s brand-new ID.4 series models adopt the voice interaction technology provided by Mobvoi, and users can realize various vehicle control functions such as conveniently regulating air conditioning temperature, answering phone calls, navigating and so on by waking up the word "Hello, Volkswagen".

  As of July, 2021, the front-mounted vehicle voice interactive system platform led by Mobvoi has been used in Audi A4L, Passat, New Magotan and other main best-selling models. At that time, it is expected that the pre-loading capacity will reach 15 million in 2023.

  "By the end of 2023, audi ag will launch a total of eight ID models in China, and Mobvoi is also committed to continuously lighting up the highlights of the entire ID family and other new Volkswagen models." Mobvoi wrote on WeChat WeChat official account.

  But also in 2021, Volkswagen China and Mobvoi parted ways. It not only emptied all its shares in Mobvoi, but also bought 50% of Mobvoi JV held by Mobvoi for $15 million.

  However, both parties signed a series of intellectual property agreements in December 2021 at the same time of equity delivery, and Mobvoi continued to provide the back-end technology of voice dialogue system.

  According to Mobvoi’s prospectus, from 2021 to 2023, its intellectual property income from Volkswagen was 3.2 million yuan, 213 million yuan and 139 million yuan respectively, accounting for 0.8%, 42.6% and 27.4% of the total revenue. In 2022, its related intellectual property agreement came into effect for the first full year, and the related income accounted for 81% of its AI enterprise solution business income in that year, and it decreased to 62% in 2023. It can be seen that the high growth of its AI enterprise solution business income came from Volkswagen China.

  It is not difficult to see that in order to cooperate with Mobvoi on-board voice dialogue system, the cost paid by Volkswagen China includes US$ 155 million investment, US$ 40 million registered capital for establishing a joint venture company Mobvoi JV, US$ 15 million acquisition of Mobvoi JV, and nearly RMB 360 million in intellectual property fees. This does not include the loss during the operation of Mobvoi JV. In 2021 alone, the loss of the joint venture company was as high as 37.13 million yuan.

  In 2024, Mobvoi will completely lose this heavy customer. According to public information, in 2024, Volkswagen ID.7 chose to cooperate with Iflytek to upgrade its brand-new intelligent voice system.

  According to the prospectus, Mobvoi is still actively expanding B-end customers. At present, it has reached technical cooperation agreements with a number of automobile companies, including testing the company’s large model and developing its applications, and developing intelligent cockpits equipped with voice assistants, smart housekeepers and voice recognition and generation technologies.

  However, with the entry of giants such as Xiaomi, Huawei, Baidu and Iflytek, the competition of car voice track has already entered the Red Sea. At present, more than 2 million cars are pre-installed with Mobvoi Voice Assistant. By contrast, in 2022 alone, Iflytek’s smart car business added more than 7.1 million sets of pre-installed shipments, and the cumulative shipments exceeded 46.1 million sets.

  In 2023, or affected by the decline in the revenue of AI enterprise solutions business, the cash flow generated by Mobvoi’s operating activities dropped from 72.44 million yuan in 2022 to 28.39 million yuan, which is another reason for further depressing market expectations besides the contraction of smart equipment business.

  03

  AIGC: What’s the color geometry, and what’s the shareholder’s income?

  While the revenues of smart devices and AI enterprise solutions are declining, Mobvoi is also rapidly moving towards the fourth stage of enterprise development, that is, the AIGC track under the big model.

  According to the prospectus, the main products of Mobvoi AIGC solution business can be divided into three categories: one is the AI dubbing assistant represented by "Magic Sound Workshop"; The second is the AI writing assistant represented by "wonderful writing" and "magic writing"; The third is the AI digital person represented by "Wonderful Yuan". At the same time, it can also provide a "DupDub" solution that integrates three types of capabilities.

  Before making a big model, Mobvoi’s products such as "Magic Sound Workshop" and "Magic Writing Works" were mainly built with exclusive algorithm models. In 2023, it launched the self-developed large model "Sequence Monkey", which has the multi-modal generation ability and can understand and generate human-like text, audio, images and videos, thus qualitatively improving the AI capabilities of different products.

  Mobvoi, for example, said that the rhythm and naturalness of the synthesized speech in Magic Sound Workshop have been greatly improved after using "Sequential Monkey". At the same time, its multi-modal generation ability also supports content creators to use innovative functions such as AI writing in short videos, which is convenient for editing and rewriting content in different styles (Figure 2).

Figure 2: Advantages of "Sequence Monkey"

  As the fist product of the company’s AIGC solution business, "Magic Sound Workshop" is a platform that uses NLP algorithm to analyze written text and convert it into natural human voice to produce AI-generated content. The tools include software dubbing, cloud editing, copy extraction and human voice processing. It provides more than 1000 sound styles and diverse sound sample combinations from external suppliers, and supports 37 languages and 15 dialects. In the charging mode, "Magic Sound Workshop" combines two modes: subscription and in-software payment. The annual membership fee is 289 yuan, and the price range of sound source is 199-899 yuan/year.

  In 2023, after joining the large-scale model capability of "Sequence Monkey", the income of AIGC solution business in Mobvoi increased from 39.857 million yuan in 2021 to 118 million yuan, and the gross profit margin increased from 88% to 92.2%, which became the biggest bright spot in the future development.

  According to the prospectus, from 2021 to 2023, the number of paying users in Mobvoi increased from 63,000 to 410,000. And with the development of services such as Wonderland, its average income from each paying user increased from 104 yuan to 248 yuan, and correspondingly, the average customer acquisition cost of each paying user also increased from 31.8 yuan to 133.1 yuan (Figure 3).

Figure 3: The scale of paying users and the cost of obtaining customers in Mobvoi.

  However, as we all know, AIGC is an exceptionally expensive track. Whether Mobvoi’s profit level can support the continuous improvement of its technology may be the most concerned issue for investors in the secondary market at present.

  According to the Artificial Intelligence Index Report released by Li Feifei’s team, it is estimated that the GPT-4 of OpenAI will use 78 million dollars worth of computing resources for training, and the Gemini Ultra of Google will cost as much as 191 million dollars. Iflytek, as one of its biggest competitors in the field of voice interaction, will spend 3.481 billion yuan on research and development in 2023.

  From 2021 to 2023, Mobvoi’s R&D expenditure was 92 million yuan, 119 million yuan and 155 million yuan respectively, which was obviously difficult to keep up with the giant’s burning progress.

  Nowadays, under the general trend that the giants have increased their AIGC, it is worth paying attention to whether Mobvoi will face the rapid squeeze of technological advantages and market space as when giants such as Huawei and Xiaomi entered the smart hardware market in 2018. How to build long-term competitiveness in the AIGC track surrounded by giants is also a problem that more small and medium-sized AIGC enterprises need to face together.

  In this listing, Mobvoi raised a net amount of HK$ 267 million, and its uses include: 44.3% to continuously improve modeling technology for model training, vertically optimize the underlying basic model by introducing technology and talents, and improve the existing program algorithm of the solution; 35.7% is used for solution development and marketing; 10% is used to seek strategic alliances, investments and acquisitions; 10% is used for working capital and general enterprise purposes.

  From the financial point of view, from 2021 to 2023, Mobvoi’s total annual losses attributable to equity shareholders were 205 million yuan, 986 million yuan and 867 million yuan respectively. If the book value changes of redeemable preferred shares and common shares are excluded, their adjusted profits in 2022 and 2023 will be 108 million yuan and 17.53 million yuan respectively.

  It can be seen that to stand out in the AIGC competition, increasing income is the most important thing in Mobvoi at present.

Eating rabbits is risky! What deadly viruses are hidden in the "game" on the table?

  According to the latest epidemic situation of pneumonia in novel coronavirus, as of 24: 00 on January 28th, the National Health and Wellness Commission had received a total of 5,974 confirmed cases from 31 provinces (autonomous regions and municipalities), including 1,239 severe cases, 132 cumulative deaths and 103 cumulative cured and discharged cases. There are 9239 suspected cases.

  The menacing epidemic has kept everyone in a state of panic. With the expansion of the epidemic, "wild animals" and "game" have once again become the focus of public attention. Earlier, on January 20th, in view of the current pneumonia epidemic in novel coronavirus, Zhong Nanshan, the leader of National Health Commission high-level expert group and academician of China Academy of Engineering, once pointed out that novel coronavirus is likely to come from a wild animal, and it is more likely to be wild animals like bamboo rats and badgers.

  On January 28th, Academician Zhong Nanshan accepted an exclusive interview with Xinhua News Agency, saying that in 2019, novel coronavirus first appeared on a bat, and scientists were looking for an intermediate storage owner in novel coronavirus.

  What is certain is that this epidemic has a great relationship with wild animals.

  Some researchers have done statistics. At present, 70% of new infectious diseases come from wild animals.

  SARS virus: The source of SARS has been proved to come from the Chinese bat, civet cats contact and infect them, and then transmit the virus to humans. If humans did not catch and eat civet cats, which were originally wild animals, the transmission chain of the virus from bats to civet cats and then to people would not have formed, and SARS would not have broken out that year.

  Ebola virus: The source of Ebola virus is wild animals such as orangutans, monkeys and bats. It is precisely because in Africa, people prey on these wild animals that Ebola virus has been transmitted from animals to people many times, and then it has caused outbreaks in human society.

  Nipah virus: Nipah virus also comes from bats, because humans built pig farms next to bat habitats, and the fruits bitten by bats and infected with the virus fell into the pigsty, and pigs were infected with the virus after eating them, and then infected people with the virus.

  Middle East Respiratory Syndrome (MERS) virus: In 2012, doctors in Saudi Arabia discovered a strange disease, which was later named "Middle East Respiratory Syndrome". The MERS virus that causes this disease was originally found in an African bat. Some dromedaries in North Africa accidentally contacted bats with viruses and were infected with MERS virus. With the trade from North Africa to the Middle East, dromedary caravans brought the virus to the Middle East, and the sick dromedaries infected more camels through nasal secretions, eventually infecting humans and spreading among humans.

  Influenza virus: almost everyone has had the flu, but the flu disease has nothing to do with humans. They come from birds. Moreover, the flu virus infects the digestive tract of birds, not the respiratory tract. The virus will "mutate", and the bird flu virus will mutate into a new virus that infects humans. However, the surface receptors of human respiratory cells are very close to those of birds’ digestive tract cells. When these new viruses mutated from birds are transmitted to humans, they cause respiratory diseases in humans, that is, "flu".

  HIV: There are two kinds of HIV: one is called HIV-1, and the other is called HIV-2. After research, scientists found that HIV-2 virus came from "mangabey with white top" in West Africa. This monkey carried a SIV virus and independently evolved into HIV-2 AIDS virus. Hunters in West Africa often kill this kind of monkey. When the monkey bites the hunter, or the butcher disposes of the monkey’s corpse, the monkey’s blood containing the virus enters the human body and will be infected with the virus. These viruses replicate themselves and gradually adapt to new hosts — — That is, humans. The HIV-1 virus has a completely different source. They come from another animal: chimpanzees.

  Baiding mangabey

  In addition, Hendra virus, Zika virus and so on, the sources of these deadly infectious diseases are all related to wild animals.

  The following small series is for everyone to learn about the bacteria or viruses that are at risk of infectious diseases carried by these common "game players" who have been repeatedly harassed.

  The greatest protection for wild animals is to stay away from them and leave their homes to them. Don’t go near them, don’t occupy them, and don’t overfish or eat.

  Protecting them means protecting us. I hope everyone can introspect, stop being willful and let the tragedy repeat itself.

  Finally, I hope Wuhan can tide over the difficulties and control the epidemic.

Do you still want to see medical drama after the epidemic?

Under the impact of the epidemic, the Spring Festival movies are deserted. Although the dramas have been updated, the publicity is still much lower than usual. At the same time, a domestic medical drama, which premiered in 2017 and scored 6 points in Douban, unexpectedly became popular under the title of "Prophecy Drama".

Emergency Doctor, directed by Zheng Xiaolong and Liu Xuesong and starring Zhang Jiayi and Wang Luodan, is also one of the first TV series donated by the State Administration of Radio, Film and Television to Hubei Province. During the epidemic, many satellite TV stations were replaying, and some netizens spontaneously watched it on video websites.

I don’t know if I don’t know, the drama "God Prophecy" is more than an epidemic. In the first episode of medical trouble, a supporting role died by the knife of the intruder. The bloody scene is inevitably reminiscent of the murder case in the Civil Aviation General Hospital.

From the national attention to violent medical injuries years ago to the passionate praise of "angels in white" during the epidemic, the group of doctors has inevitably become the focus of recent hot discussion, and the content of medical subjects has also received more attention.

Judging from the audience’s interest and market inventory, domestic medical drama seems to have finally reached a new turning point after the setbacks in 2017.

Domestic medical drama, what’s the difference?

Similar to the theme of criminal investigation, medical theme, as an important branch of professional drama, has become quite mature and stable overseas. Doctors are an indispensable industry in people’s daily life, but they are easily unknown. Taking them as the object of description not only meets the realistic needs, but also caters to the audience’s prying psychology to some extent.

At the same time, the hospital faces birth, illness and death, and the human feelings are warm and cold. There is huge room for drama. Light can be like "Grey’s Intern", showing growth and workplace; It can be like "The White Tower", which describes the complexity of human nature. Su Shuang opened, such as the Japanese drama "Dr. X: Surgeon Daimon Michiko"; Hard core is deep, such as the short-lived and high-scoring American TV series Monday morning.

In domestic dramas, medical drama’s output is not high, but there were some works of conscience in his early years. For example, Never Give Up, also directed by Zheng Xiaolong, Infinite Vitality, created by the original crew of Six Major Crimes, and The Doctor’s Benevolence, directed by Dongyu Fu, the director of Action to Break the Ice.

The most influential domestic medical drama in recent years is Mind Mind in 2012. The screenwriter Liu Liu’s grasp of realistic themes and social topics is indeed in place, and all the actors are acting online (although it seems that this lineup is really toxic now).

After the popularity of Mind Art, the market followed suit in succession. In 2014 and 2015, there was a small outbreak in medical drama. In the past two years, four films and three films were broadcast in medical drama, including Distance to Love, Obstetrics and Gynecology of Love, Young Doctor, Growing Up and so on.

In medical drama during this period, the leading role began to be younger and idolized, and the professional details were increasingly controversial. In 2014, Lilac Garden conducted an online survey involving 2,012 doctors, among which 79.4% of the respondents thought that there were many mistakes in domestic dramas.

Medical drama was temporarily absent in 2016, and made a comeback in 2017, under the circumstances that practitioners made mistakes and the media discussed it hotly. Bai Baihe’s Justices Seeker and Wang Luodan’s "Emergency Doctor" are separated from each other. There is also a Pediatrician, starring Leo, who was not famous then.

At this time, the audience’s spit on medical drama has not only pointed to the professional details, but has risen to the level of personnel. Simply put, the protagonist is too virgin, and the returnees love to pretend "beep-".

Why do most domestic professional dramas annoy audiences, especially practitioners?

Distortion of professional details and water injection in love are appearances; In a deeper sense, it is the creator who failed to give the role professionalism (or the creator’s own understanding of professionalism is not in place? After all, most of them are "people who have never been to work"). As a result, it is often the case that the protagonists are emotional and morally kidnapped by each other without a word, regardless of their professionalism.

Different occupations have their own unique ethics and ways of doing things, and professional dramas should be properly displayed to better portray characters. Instead of taking the most superficial primary school students’ three views on all stories, creating a confrontation between "sticking to your duty" and "being a good person", taking exceptions and sacrifices as inevitable, being vague about the structural problems behind the phenomenon, or not thinking at all.

Documentary and online literature have ushered in a medical fever.

Unlike domestic dramas, which are tied behind one’s back, stupid and difficult to explode, in recent years, the "medical fever" in the field of documentaries and online articles has been maintained for quite some time.

Compared with TV dramas and reality shows, authenticity and professionalism are the biggest advantages of documentaries, and it is a great plus for medical subjects. According to media statistics, the average score of douban, a domestic medical documentary, was as high as 9.2 from the 2013 Ten-Year Festival of SARS. Among them, the well-known ones include Human Life, which shows the relationship between doctors and patients, Birth Gate, which focuses on obstetrics and gynecology, Emergency Room Story and Emergency Rescue 120, which focuses on emergency treatment, and the popular science Two Hundred Years of Surgery.

During the Spring Festival this year, Iqiyi launched a documentary called Chinese Doctors, which has achieved a high score of 9.2 in Douban. According to the data, the film was shot and produced by the film crew in different departments of obstetrics and gynecology, emergency department, oncology department, anesthesiology department, operating room, ICU and so on in six large 3A hospitals all over the country, trying to show the real doctor’s daily life with calm lens language, which is more meaningful in the current public opinion environment.

There are also many types of doctors or medical elements in the net. The most basic thing is that in female frequent romances, there are not a few people whose protagonists are doctors. After all, white coats are also the temptation of uniforms. Traditionally, through the passage, the protagonist shocked the ancients by modern accumulated medical knowledge, stirred up the storm, or upgraded by medical skills in the palace fight (after all, the abortion team in the palace only knows something about musk and saffron), and finally became a generation of medical concubines.

In addition, Hard Sugar Jun also mentioned "The Great Doctor Ling Ran" under the reading article before. The novel tells the story of a graduate who entered the hospital accidentally acquired the mysterious system and embarked on the road of technical cattle. Among them, the characters are distinctive and even exaggerated like cartoons, but the description of the hospital environment and the world is very realistic. The novel involves a lot of professional medical knowledge, and describes the "technicality" of surgeons, which has been affirmed by many professionals and has a certain interest in popular science.

The popularity of "The Great Doctor Lingran" has also led to the rise of a new batch of "technical stream medical articles". There are also "Operation Live Room", "I can see the status bar" and so on.

It is difficult to define this kind of works simply by the label of realism or non-realism. Many times the problem is realistic, but the means to solve the problem is unrealistic, and the sense of coolness comes from this.

More than half of the new medical drama was intercepted by the epidemic.

In fact, judging from the market inventory, in 2020, there will be more than ten films to be broadcast and filmed involving medical elements. Its lineup is also quite eye-catching, with 85 small flowers and delicious fresh meat. It is really a gathering of the most popular and topical actors at the moment, and the marketing number began to count and vote early. Unfortunately, nearly half of them were turned on at the end of last year or January this year, and filming has been suspended due to the epidemic.

Among them, Yang Mi and White’s Thank You Doctor (started in November 2019, which was the earliest time to stop filming medical dramas), Stephy and Yang Shining’s Take a Deep Breath Together (Foreign Aid Medical Care), and Huang Jingyu and Li Qin’s Dear Military Dress (Special Forces and Female Military Doctors).

The second level includes "We started to fall in love from marriage" starring Zhou Yutong and Simon; And "My Little Lucky" starring Fair Xing and Daddi Tang, the urban sweet pet, did not run away; In addition, there is a costume drama "Great Traditional Chinese Medicine" starring Xia Yu. According to the master, it took four years to prepare for the drama, and the Chinese Society of Traditional Chinese Medicine was invited to provide guidance. Unfortunately, it is a pity.

There are also two new dramas that were just finished in January 2020. One is the military emotional drama "You are my fortress" (swat elite and female doctor), which is produced by Golden Shield Film and Television Culture Center of the Ministry of Public Security, the drama cool communication of Huace Keton and Leben Culture, and starring Sandra and Bai Jingting. The other one is produced by Mango TV, starring Yuxi Zhang and Ding Yuxi, "The Color is Strong" (genius doctor and the Popular Floret).

There are also three new dramas that were filmed in 2019, including The Great Pediatrician starring Chen Xiao and Olivia (finished in May), Little Doctor starring Dong Zijian and Jenny (finished in July), and Please Teach Me for the Rest of My Life (finished in November).

Judging from the lineup and plot, all three plays have the potential to be stars. In addition, the epidemic has affected the shooting of new dramas and the broadcast of TV stations, so the first two dramas may have the opportunity to meet the audience as soon as possible. The prospect of "Please Give Your Advice for the Rest of Your Life", in which both male and female stars are at their peak, is even clearer. It has been confirmed that it will be broadcast on Hunan Satellite TV and Tencent video, and the schedule is undecided.

However, it is not difficult to see that most of these medical dramas are not traditional medical industry dramas, but idol dramas in which one party is a doctor, and there are even collisions. Generally speaking, unless there is really a big gap in shooting quality, it is bound to be who broadcasts first and who is more dominant, which is also a lot of pressure for stopping filming.

Of course, medical drama can and should do more. The outbreak of new pneumonia was in a period of highly developed information, which was quite different from the experience of SARS in 2003. Even squatting at home, we can get in touch with real people and stories from the front and back, as well as various voices with different positions, which makes people anxious, painful and sad, and forces us to think.

If this kind of thinking can be embodied in the writer’s pen, deduction is not only a unique way of recording the times in film and television, but also a social responsibility that literature and art should bear.

China cooking master Dong Jidu died of illness — China News Network Sichuan News

  Zhongxin. com, Sichuan News, January 24th (Reporter He Yuqing) The reporter learned from the Sichuan Historical Society’s Sichuan Oral History Committee on the 24th that Dong Jidu, a master chef of China, former head chef of Jingchengyuan Restaurant of Chengdu Catering Company and co-chairman of the Association’s professional committee, died in Chengdu at 18: 00 on January 23rd, 2023, at the age of 79.

  This culinary master who wrote in the Annals of Sichuan Cuisine is not only proficient in Sichuan cuisine, but also bypasses western food and western pastry technology. His representative dishes include poached squid, dried fish wings, preserved chrysanthemum abalone, dried deer tendon, pigeon eggs with hoof swallows, and young chicken tofu pudding.

Dong Jidu is very supportive of the oral history of Sichuan cuisine.
Dong Jidu is very supportive of the oral history of Sichuan cuisine.

  Dong Jidu went to Chengdu Yaohua Western Food Department as an apprentice in 1961, and studied in Yulong Restaurant Chef Training Class in 1964, under the guidance of famous chef Xie Shaoyun. Later, I worked as a chef in Rong Paradise and Yaohua Restaurant. In 1979, he was admitted to Chengdu Senior Chef Training Course. After graduation in 1981, he was assigned to work in Jingchengyuan as a chef, and studied under the famous teacher Liu Duyun. During this period, he went to Jingchengyuan Restaurant in New Jersey, USA as a chef for two years in 1983. After returning to China, he also served as a professional teacher of Sichuan cuisine training class of the city catering company, and participated in the compilation of several Sichuan cuisine cooking textbooks. He has participated in the evaluation of Chengdu chefs’ titles for many times and was awarded the title of Chinese Senior Cooker Appraiser.

  In recent years, many Sichuan cuisine masters who witnessed the development history of Sichuan cuisine have passed away one after another. In order to carry out the rescue excavation of Sichuan cuisine culture and promote Sichuan cuisine to the world better, the Sichuan Historical Society’s Sichuan Oral History Committee was established in November 2022. Dong Jidu is also one of the co-chairs of the Sichuan Historical Society’s Sichuan Oral History Committee.

  In an interview with Dong Jidu recorded by the Special Committee on Oral History of Sichuan Cuisine of Sichuan Historical Society, this Sichuan cuisine master once revealed "the secret of learning to cook Sichuan cuisine"-"If you want to learn technology, go to the place where the old masters drink morning tea".

  Dong Jidu recalled that there was a Caotangzi tea shop in Dajin Street, Chengdu, where masters such as Liu Duyun, Zhang Songyun, Ceng Guohua and Mao Qicheng loved to drink tea. He used to go to the tea shop with Wang Kaifa and Li Defu in the morning to have tea with the grandfathers, and listen to their dragon gate array of Sichuan cuisine. At that time, Zhang Songyun had a sentence that impressed Dong Jidu-"In any case, we should make the best use of our raw materials and not waste them".

  In 1983, 39-year-old Dong Jidu was sent to Jingchengyuan, New Jersey, USA as a chef. At that time, Wang Development was also working as a chef in the American Paradise. On vacation, Dong Jidu hitchhiked to Rongyuan to discuss cooking with Wang Kaifa, and they often discussed it late into the night.

  "The departure of Master Dong Jidu makes us feel that the oral history of Sichuan cuisine is imminent, and it is necessary to race against time to record and preserve the cooking essence of more Sichuan cuisine masters in time." Li Zuomin, Secretary-General of the Special Committee on Oral History of Sichuan Cuisine, said that Dong Jidu was very supportive of oral history before his death, and donated the Sichuan Cuisine books and used Sichuan Cuisine utensils he participated in, leaving his mark on the development history of Sichuan Cuisine.

Baidu Post Bar-Beginner Chapter of Searching Skills for Dry Goods

In the impression of many people, Baidu Post Bar is a place with rich content, but some people are not very clear about how to find "dry goods" in the post bar. Rodin said: "There is never a lack of beauty in life, but a lack of eyes to find beauty." In fact, this sentence is also applicable to Post Bar: Baidu Post Bar never lacks dry goods, but only lacks the correct way to find them.

This small series of disgusting analysis brings you introductory and progressive articles on the use skills of Baidu Post Bar, hoping to help all those who seek dry goods to be a great beast to avoid "water"! Because there are many dry goods, in order to make it easy for everyone to master them, today I will introduce the introductory article on the skills of using Post Bar-clarifying interests and needs.

As a social platform with tens of millions of interests, Baidu Post Bar not only provides a wide selection space for long-term users, but also makes beginners a little dumbfounded: "Where should I start with so many themes and high-quality content?"

It can be said that for most users who are new to the post bar, the feeling of "scratching their heads" is caused by not finding a theme that meets their tastes and interests. Therefore, the meaning of the introductory article lies in: make clear the information category you need and find the corresponding topic!

The easiest thing to divide is the theme with "interest" as its dimension. Painting, singing, flowers, grass, small animals, idolize, etc. There are more than 17 million topics in the post bar, and you can find the same hobby here no matter how high or cold your interest is. As long as you have a clear interest, you can find the corresponding topic by searching for keywords or selecting the post bar classification on the left side of the post bar homepage.

How to find dry goods after entering the interest bar? Take "Hand-painted Bar" as an example. When you enter the bar, you can click on the "Boutique" tab to quickly browse the high-quality dry goods stickers produced by a large number of cattle people in the bar! You can also select sub-items such as "Resource Tutorial", "Friends Drawing" or "Boutique Map" by sorting labels. In the boutique stickers and different categories of sub-items, you will find that the post bar is simply crouching tiger, hidden dragon and unfathomable! Xiaobian casually PO a few posts, you feel …

In just one "hand-painted bar", there is everything from 3D wall painting, figure sketch to scenery sketch. Who dares to say that there is no dry goods in the post bar? Other art themes, such as "Watercolor Bar", "Oil Painting Bar", "Sketch Bar", "Illustration Bar" and so on, are countless in Xiaobian, so it depends on your interest!

Baidu Post Bar also has many topics other than hobbies, such as local bars and campus bars. I miss my alma mater for a while, and it may be the fastest way to understand the campus dynamics by posting it to find the theme of my alma mater.

At the same time, many students also solve their difficulties in learning through the theme of "College Entrance Examination Bar", "Senior High School Physics Bar" and "Senior High School Mathematics Bar". For example, in "Math Bar in Senior High School", there are many bar friends who post online questions for long-term obligations, provide math review materials for different grades, and sort out knowledge points and error-prone questions. There are even university parties who have already graduated. Out of their love for mathematics, they write their own test papers and provide them to the bar friends for discussion.

If you have a wide range of interests and don’t have a specific interest demand at the moment, some comprehensive fun bars can also satisfy you, such as Li Yi Bar, God Reply Bar, Connotation Bar, Skimming Bar and so on. This kind of theme bar’s boutique dry goods stickers may not be interested, but the theme is clear, but if you stroll around these bars for a few times, you will definitely stand at the forefront of network hotspots.

The above is the content of the introductory article on the use skills of Baidu Post Bar. From hobbies to study courses, from hometown, alma mater to fashion life, Baidu Post Bar can give you the most nutritious information and content. Are you more confident in fishing for dry goods on the post bar? Then what are you waiting for? Come and post it and try it!

Stop saying that you don’t know the meaning of BMW logo.

Even if they are the same, there will be "320i" and "320Li" at the rear of the car. You should know that those marked with "320Li" at the rear should also have the word ""because it is a long version. If you know something about it, you should also know that ""and "iDrive" represent two different kinds. However, it’s a little hard for you to look at a logo at the end and make it clear that it’s consistent. Will it be a little difficult for you not to check the information?

For the digital label at the tail, many people just know its meaning. Simply put, the bigger the last two digits, the better the car will be. Someone also said that the last two digits represent the size of the engine, which may make sense on the 316i and 320i/320Li, but the 328i and 328Li are also equipped with the same 2.0TN20B20 engine. Why are the last two digits so big? This is because their engine tuning is different, but how can we see whether the engine tuning of this model is high or low from the digital mark at the tail? Please see below.

Figure: The previous generation of 316i is unprecedented abroad. "16" means equipped with a 1.6T low engine and 136Ps.

Figure: "20" means equipped with a 2.0T low engine, 184Ps.

Figure: "25" indicates that it is equipped with a 2.0T medium engine with 218Ps.

Figure: "28" is equipped with a 2.0T high engine, 245Ps.

Figure: "30" means equipped with a 3.0L naturally aspirated engine, 258Ps. Yes, the "D" at the back also means using Diesel power.

Figure: "35" means equipped with a low engine, 306Ps.

Figure: "40" means equipped with a high engine, 320Ps.

Figure: "50" means equipped with 4.0T or 4.4T engine, 408Ps or 407Ps.

Figure: "60" means equipped with 6.0T engine, 544Ps.

Take 320Li as an example, the first letter "3" indicates the series of this car, the second part "20" represents the engine version used by this car, "L" stands for the longwheelbase, and "I" stands for the fuel-injected model, in which F30 is the short shaft version and F35 is the long shaft. Including 316i, 320Li, 328Li, 335Li;; 320i、328i、335i、320i、328i、335i。

There are no so-called "long" models in foreign countries, but only F30, F31 and F80. However, when F35 arrived in the domestic market, it was treated more warmly than F30. This change may be funny to us, but it is more because F35 can better capture the hearts of Chinese people.

Figure: 118i represents the 1.6T high engine, 170Ps. In contrast, the 116i is equipped with a 1.6T low engine and 136Ps. The "I" at the end indicates the engine.

Although 320i and 320Li are the same, they are still different in code name. The code name of 320i is F30, which means short axis version. The code name of 320Li is F35, which means long axis version.

Figure: 320i(F30). "20" means equipped with a 2.0T low engine, which is 184Ps.

Figure: 320Li(F35). It is also equipped with a 2.0T low engine of 184Ps, and the difference is this "L".

Figure: 335Li(F35). Similarly, this "L" has also sold its domestic identity.

Figure: The letter "C" in 645Ci stands for "Coupe" two doors, and the last use of this name was on the models of (E46) and (E63).

Figure: 330dTouringModernLine(F31), "T" means Touring (Travel Edition), including Wagon and Eseate.

Figure: Ti model of (E46). The so-called "Ti" refers to the hatchback.

Photo: 530xi(E60) is equipped with the 5 series of the system, so you will also see the model with XXXXi written on the rear of it in the early days abroad.

I don’t know if readers will understand that Xiaobian mixed the M series in the chapter of "letter meaning", because the model marked by M represents the high-performance version of the car series. The company (German: BMWmbH), formerly known as BMWMotorsportGmbH, is a subsidiary of the German manufacturer group, and its earliest history can be traced back to 1972. Originally known as M Department, the company was originally a special department specially set up to participate in motor racing, but later it gradually turned into a unit specializing in the development of original high-performance cars (M series) and original performance modification kits. In 1992, the M department was separated and a subsidiary, BMWMotorsportGmbH, was established, and the company name was simplified the next year to become today’s BMWmbH. The M-series models are original high-performance versions for some of its models. The so-called "M" is taken from the initial letter of "BMWMotorsport", and the models currently on sale include: M2, M3, M4, M5, M6, X3M and X4M.

Figure: The former BMWX5M(E70).

Photo: Surely no one will think it is a real 318i?

Photo: "CSL" stands for Coupe, Sport and Lightweigh. This series of cars is also a pure driver’s car and was born for the track. M3CoupeCSL(E46) produced only 1,400 vehicles from 2002 to 2004.

The early four-wheel drive was not called ADB-X, which followed almost contemporary products. Therefore, the early ADB-X four-wheel drive system is very similar.

Figure: logo.

The early ADB-X four-wheel drive system also adopted three open types: front, middle and back. Power is distributed to each one through these three, and when there is slip, the differential limit is also realized through ABS. But later, the ADB-X was also upgraded to Xdrive, just like the reason for the evolution from the first generation to the second generation, and because of its poor driving performance on the road, Xdrive was introduced in order to upgrade it.

At present, the most widely used intelligent system in China is X series, so we can see its logo from the sides of X3, X4, X5 and X6. However, there are also assembly systems on the 640d and M550d, but this model is extremely rare in China, so you don’t have to worry about it. There is also the logo of sDrive(Rear-wheeldrive), which appears on X118i and mainly expresses the meaning of rear-wheel drive. However, some people may ask, almost all of them are rear-wheel drive, why are there no such signs in the 3 series and 5 series? The manufacturer’s current explanation is that X1 is the only model with rear-wheel drive in the X family, so it is highlighted by sDrive to see the difference with the four-wheel drive models used. As a classic Roadster, Z4 uses sDrive to emphasize its rear drive, dynamics and agility. Therefore, compared with other models, X1 and Z4 want to highlight this point (the above is the official reply of BMW).

Figure: sDrive refers to the rear-drive model. Such as sDrive35i and sDrive18i I.

The first generation iDrive, which appeared in the 2001 model, became the biggest selling point of the 7 series that year. In addition to the characteristics of the times, it also interprets a brand-new, simple, safe and convenient concept of future driving.

At that time, the new 7 Series can provide about 700 functions. If all kinds of switches and function keys are arranged in the traditional way, it will not only be dazzling, but also almost impossible. The innovative solution is to divide these 700 functions into three categories: various operations related to driving, including shifting gears, are reasonably distributed around the steering wheel; Other commonly used basic functions are kept on the computer and operated by traditional switches and buttons, including car phone, air conditioning routine control, audio system routine control, etc. A large number of other functions, including communication, remote network service and some important and very practical comfort functions, are set in a highly integrated central control center. Although there were different voices in the market when it first appeared, soon, other major brands successively introduced similar control concepts.

EfficientDynamics translated into Chinese means "efficient power", which includes many specific technologies, such as the extensive use of high-rigidity and lightweight materials and the introduction of HPI high-precision in-cylinder direct injection engine technology, ranging from diesel engines to hydrogen energy in the future, all of which belong to the category of efficient power. Nowadays, all the new models in the series are marked with engine start-stop systems, systems, and many intelligent schemes to reduce and reduce carbon dioxide.

Figure: The comprehensive use of lightweight but high-strength materials not only improves the economy, but also enhances the driving pleasure. In addition to the car body, it is also planned to design the future aluminum alloy forging into a hollow shape, and inject silicide foam into it to reduce the weight while keeping it hard.

Figure: N20B20 engine with this technology is more efficient than the previous generation 3.0-liter inline six-cylinder naturally aspirated engine.

Except for the old models, from the smallest MINI to the largest X5, a set of automatic transmission system named STEPTRONIC is basically used. This gearbox comes from ZF, an expert, and it is also the most popular automatic transmission system in the world. Although STEPTRONIC has a manual gear shifting mode, it is actually the same as other similar gears, but it has done some tricks in computer control. In control, several electromagnetic valves are used to force the oil circuit to open or close, so as to realize manual control to change different gears, which is a far cry from the actual sense. Below the word S is the mode selection key, and there are as many as 11 shift modes.

Figure: There is still a slight difference between the S and other models, that is, the upshift is in the back and the downshift is in the front. These designs are very in line with human driving mechanics.

Figure: The simplest S work flow chart.

A year after E36 M3 was retired, the new E46M3 was born. At first, it was only equipped with the traditional six-speed gearbox, but in 2002, a set of wholeheartedly improved semi-accessories named SII was listed as an option for M3 owners. This system changed the shortcoming of slow gear shifting, and under the control of sophisticated computer management system, the gear shifting speed could reach the ultra-fast level of 0.08 seconds at the earliest. You know, an ordinary driver who has been trained in professional racing has a shift speed of only 0.3 seconds, which is several times faster than that of a professional racing driver. It can be said that it is impossible for ordinary people to use cars in ordinary streets, but it gives people this opportunity.

Today’s car series is no longer so "simple", and its 2 series and 4 series are split from the original 1 series and 3 series. As for why the models belonging to the same car family should be "separated", the benefits of this move to the car factory are more that the positioning of coupe/convertible models can be further raised and the pricing can be improved. No matter how the car is divided, the meaning of letters and numbers will not change.
